I doubt you can retrieve the data source by including a connection string to the source of an asp.net controlcolumns are usually bound in code behind. Did you check module settings for selecting columns, whether it contains username as well?

Sebastian under http://www.xxx/Admin/SecurityRoles.aspx if I go to the Settings I can see a few options but I'm not sure if the 'Name' refers to the username. (FirstName) refers obviously to the first name. In any case, i have selected everything but only three values appear: Username (which is wrong - its the full name), Effective date, and Expiry date.
